Abstract

통신 포드 상태를 체크하여 일정 시간 동안 데이타가 수신되지 않을 경우 통신 불능 상태로 판단한 후 통신 동작을 초기화하여 다시 데이타의 송신요그를 반복하므로 장시간 동안 통신 상태가 불량한 엔진 시동 초기에도 엔진 제어 장치의 데이타 모니터링 동작을 실행할 수 있도록 하는 엔진 제어 장치의 데이타 모니터링 장치 및 그 방법을 제공하기 위하여, 엔진의 제어 동작에 따라 저장되어 있는 데이타의 상태가 변화하고, 외부에서 통신 요구 신호가 수신되면 데이타 통신 상태로 동작 상태가 변화되어 데이타 통신 동작을 실행할 수 있도록 하는 엔진 제어 장치와; 상기 엔진 제어 장치와 연결되어 있고, 엔진 제어 장치에의 데이타 통신을 위한 요구 신호와 통신 동작을 위한 초기 동작을 실행하며, 정상적인 초기 동작이 이루어지며, 상기 엔진 제어 장치로 데이타 송신 요구 신호를 송신하여, 설정 시간 내에 데이타가 수신되면 데이타 통신 동작을 종료하고, 설정 시간 내에 해당 데이타가 수신되지 않을 경우 데이타 송신 요구 신호를 재송신하는 통신 제어 장치를 포함하여 이루어져 있다.If data is not received for a certain period of time by checking the status of the communication pod, it is determined that the communication is incapable and then initializes the communication operation and repeats the data transmission yog. In order to provide a data monitoring device of the engine control apparatus and a method thereof for executing the operation, the state of the stored data changes according to the control operation of the engine, and operates in a data communication state when a communication request signal is received from the outside. An engine control device for changing the state to execute a data communication operation; It is connected to the engine control device, performs a request signal for the data communication to the engine control device and the initial operation for the communication operation, the normal initial operation is made, by transmitting a data transmission request signal to the engine control device And a communication control device for terminating the data communication operation if data is received within the set time, and retransmitting the data transmission request signal if the data is not received within the set time.
